. This invention relates to filling 'replenishi ing looms, and more particularly to the shuttle'feeler mechanism. V f Y It is now the ordinary practice to provide filling replenishing looms with a shuttlefeeler whichon call for replenishment of lilling ismoved from a frontwar-d t-oa rear? ward position to ascertain if the shuttle has been properly boxed `and ifnot `to prevent.

The invention and novel features thereof` will bestbe made clear from; the following description and the accompanying drawings of one good practical form thereof.

In the drawings Fig. 1 is a` sectional side elevation of por-V v tions of a filling replenishing loom provided Vwith the present invention, Vthe shuttle feeler being shownasin its-rearward shuttlefeelingposition; and I.

Vprovided the dog 6 has been moved into the path of the bunter on Acall for replenishment offillinggf f: Y f f The,` lay 8 is shown ascarriedby the usual lay swords 9.and is provided with the shuttle boxlO, and the parts thus far described may be of usual construction which being now 1 well understood inthe art need` no .further explanation. i

feelersupport 11 which is shown in ythe present instanceoftheinvention as connectedtor .the loom'jframe lby a pivotal mounting 12, whereby theshnttleffeeler support is'capable otfrontward sv'vinging.movement about its` a trontward f 15, thbther `end of the spring being con- S Y M Y A, nected at`16to aixed support which is ynfiounted upon the-loomN frameor movement towards. andfrom thel front-fof the loom, jis normally held i'njitsf i e point onthe loom frame, :Y the construction' being such' that, lthe` spring' 15 normallyholds the shuttle feeler-support VVpermissive spring 15.',V a

In orderfthat the shuttle ereler support'll maybe maintainedrin its proper 'rearward lee NT 'oFFl-cn structlon and have mounted thereon the supeA Y Y 1 l so i Mounted on the loom .frame 1 1s a shuttle position during the weaving operation, a stop is provided for determining the rearward position of the shuttle feeler support. In the present instance of the invention, the stop consists of a block secured to the loom frame by a bolt 18 and the shuttle eeler support is provided with a cooperating stop constituted by a shoulder 19 which overlies the stop 17 when the shuttle eeler support is in its normal rearward position, as indicated in Fig. A1.

The shuttle 'ieeler support 11 carries the shuttle eeler 2O which is pivotally mounted on the shuttle feeler support at 21, and the shuttle feeler extends upwa-rdly,fas usual, and has its rearwardly extending end portion provided with the shuttle engaging jaws, which .also vconstitute thread positioning means to position the thread for the action of the thread parter or thread parter and clamp. t

The thread parter 23 has onefof its parting members pivotally mounted on the shuttle eeler at 2i and extends frontwardly to form the toe 25 which `may be engaged by the lay or A a part carried thereby for operating the thread :parten The thread parter may be of any of the vnow well-understood constructions and needs no further explanation.

Secured to the shuttle feeler 2O at 2G is the slotted arm 27 which engages a spin 28 eitending from the dog G, the construction ybeing such that should the shuttle freeler be moved rearwardly on cal-l for replenishment of iilling, the dog 6 will be moved into the position indicated in Fig. 1, to engage the bunter 7 carried by the lay, to thereby operate the transferrer. a

Mounted on the loom trae is the transverse or rock shaft 29, as usual, and Secured to the rock shaft is the arm 30, the rear end portion 31 of which overlies a -pin 32 carried by the shuttle teeler. Cooperating with the end 31 of the arm 30 is yielding member 33 which is shown as constituted :by a rockin-g t member mounted upon the arm at 34 and having its trontwardly extend-ing end 35 connected to a spring 36the lower end of which is secured to a pin 37 on the loom frame, with the result that should the shuttle eeler I'. be moved rontwardly by engagement with the shuttle, the'member 33 will yield against the stress of the spring 36, as indicated in Fig. 2. i

Preferably the spring 15 is stronger than the spring 36, so that should the shuttle feeler contact with an improperly boxed yshuttle as the lay moves ront-wardly, the shuttle eeler will irst be moved frontwardly about its pivotal mounting- 21 on the shuttle feeler support and then the shuttle ee'ler `support 11 will come into action and .permit the shuttle eeier to be moved further irontward by tilting or swinging movement of the shuttle feeler support, thereby providing sufficient front'ward yielding movement of the shuttle ieeler by the combined action of the shuttle feeler support and shuttle feeler, to prevent damage or breakage of parts.

Extending upwardly from the shuttle feeler support is the guide member' 38 which directs the4 shuttle feeler in its path of movement towards and from the front of the loom.

During normal weaving operations between calls for replenishment of filling, the shuttle feeler occupies its rontward or 'moperative position, as usual, while the shuttle feeler support occupies its normal rearward position under the action of the spring 15, and should the shuttle eeler Contact with an improperly boxed shuttle as the lay moves rontwardly, the shuttle feeler will yield at its pivotal mounting 21 on the shuttle feeler support against the stress of .the spring 36, and as the lay moves rontwardly the shuttle feeler support will be turned about its pivotal mounting 12 against the stress of the spring 15, thereby permitting sufficient frontward .movement of the shut-tle feeler to prevent injury or breakage of parts.

On call :for replenishment of iilling, the rock shaft 29 will be turned or rocked, thereby moving the shuttle eeler to -its rearward shuttle feeling position, land if at this time the shuttle eeler Aengages an improperly boxed shuttle as the lay moves rontwardly, the shuttle feeler will be first moved frontwardly against the stress of the spring 36, as indicated in Fig. 2,l and the shuttle feeler support will also swing frontwardly about its pivotal mounting 12 to thereby permit the shuttle feeler sufiioient frontward movement by the oncoming improperly boxed shuttle to prevent injury or breakage ofparts, and since therdog 6 is connected to the shuttle feeler as above described, the shuttle feeler will swing the dog out of operation with the oncomingl bunter 7 and lling replenishment will not be edected.

The invention herein described provides a simple and effective means for sufficient frontward movementl of the shuttle eeler by an improperly boxed shuttle to avoid the in- `iur-ies and breakage off parts that now frequently occur under these conditions, and while the present embodiment of the invention shows the shuttle feeler provided with a thread cutter, this may or may not be used within the true scope of the present invention.
